There has certainly been enough times for multiple technological civilisations to have risen and fallen in Earths history but the questions is where is the evidence od these civilisations?
When we to see artefacts of civilisation turning up in cretaceous strata we can start hypothesising about extinct civilisations.
Just because something can happan does not mean it did happen.
